Portable housing for a sewing machine

The invention relates to a portable housing for a sewing machine. So far, the portable cases for sewing machines have been bulky and heavy as these portable cases cover the whole Components of the sewing machines protected, and were connected to the machine, so that a high total weight resulted. in the In general, a sewing machine was hinged to one side of the base body of the portable housing as it was to a Machine table is articulated. The hinge devices, as well as other ancillary devices, such as the lock and the Carrying handle, the weight.

The portable housing had to be made of a material strong enough to withstand the full weight of the sewing machine to record. Along with other complementary operations to connect parts, the traditional portable Housing expensive and heavy.

According to the present invention, disadvantages of the conventional portable housing can be eliminated. The portable case should be simple in construction, light in weight and small in size be. It should also not be burdened with the weight of the sewing machine. The sewing machine should also use the Base body of the portable housing be firmly connected. The The handle of the sewing machine protrude when the sewing machine is covered. Furthermore, a circular one can be used for the flywheel Opening can be provided in a narrow side of the cover of the portable housing.

Articulation, holding and locking devices of the conventional Art can be omitted. Since the housing no longer has to take up the weight of the sewing machine, it can be made of thin and cheap Material can be produced easily and without effort.

The further properties and advantages of the invention emerge from the following description of the structure in connection with refer to the accompanying drawings, in which the following is shown:

Pig. 5 is a section through the base body along the line V-V of FIG. 4, partly broken away, with a Bolt is shown connecting a sewing machine to the base of the portable housing.

Pig. 6 shows a stud screw screwed into the rear part of the machine bed.

Ό '

Figures 1 and 2 show a sewing machine 1, which is about right-angled hollow main body 2 comprises, which has a worktop on its upper side, which with a stitch ~ plate and a knife gate valve. On the base body 2 is a stand with arm 5, which is in a head 6 ends. The sewing machine has a handle 14 attached to its top and a flywheel on its right narrow side on. The needle bar mechanism 31 is in the head. A snare catching mechanism (not shown) is provided in the hollow base body 2 below the worktop 3.

According to FIGS. 5 and 6, two are arranged at a distance from one another Projections 28, only one of which is shown, are integrally formed on the underside of the worktop 3 and adjoin it their rear end. Each projection is provided with a lateral bore 29 which extends through the entire projection of its back extends so that the sewing machine on a conventional portable housing or machine table with the help of articulation devices can be attached. Each projection is provided at the bottom with a vertical threaded hole 32, which the lateral bore 29 crosses. A bolt 23 is screwed into the vertical threaded hole 32 of the projection 28.

According to FIGS. 1 and 5, there is a portable housing according to FIG Invention of a substantially rectangular hollow base body 11 to accommodate the base plate 2 of the sewing machine and a lid 12 which completely covers the sewing machine. As

609813/0778

in Pig. 4, “the base body 11 has a bottom 13> a front 18 and a rear 19 longitudinal side wall, which extend vertically from "both sides of the base, as well as narrow side walls that extend vertically from the opposite one Extend from the side of the floor and connect the front and rear side walls. The hollow main body 11 is provided on its right narrow side with a compartment 30 for accommodating sewing equipment parts. Between Ribs 35 are attached to the bottom 13 on the front and rear longitudinal side walls in order to close the entire base body 11 consolidate. At the four corners of the base body 11 guide parts 15 are provided which support the worktop 3 below * The bottom 13 of the base body 11 is under the The loop catching mechanism is provided with a rectangular opening 16. The loop catching mechanism remains for the operator accessible to the sewing machine. The opening 16 can be closed by a slide 17 which, as shown, in Bottom 13 of the base body 11 is attached. The bottom is. as shown at 20, graduated at two spaced apart Places next to the rear side wall (19) of the base body 11 and vertically opposite two from each other at a distance located projections 28 are arranged, which are located on the underside of the worktop 3. Projections 22 with centrally arranged vertical depressions are attached to the gradations 20. That way the sewing machine can be firmly connected to the hollow base body 11 of the portable housing by means of two bolts 23, which in the vertical Engage recesses 21 of projections 22 from the underside of base 13; then they will be in the appropriate Threaded bores 32 of the projections 28 in the underside of the Worktop 3 screwed, the lock washers 34 between the underside of the gradations 20 and the heads 33 of the Bolsen 23 are inserted.

The lid 12 of the portable housing 10 is, as shown, provided with an elongated opening 24 through which the sewing machine handle protrudes from the top wall when the cover is placed on the base body 11. The lid also has front and rear side panels on either side slope outwards at the top of the lid. The right narrow side of the lid 12 has its upper part a circular opening 25 so that part of the flywheel 7 of the sewing machine can protrude through the narrow side when the Lid 12 is placed on the hollow base body 11. The cover 12 has a splash 26 on its underside. It surrounds it the lower end of the lid and is slightly curved outwards, so that the upper border 27 the hollow base body 11 encloses when the cover is placed on the base body. In this way, the lid 12 closes the sewing machine together with the hollow base body 11 completely and the sewing machine can be touched in the closed state of the handle 14 of the sewing machine protruding from the portable housing 10.

As is apparent from the above description, the portable case according to this invention need not be substantial Withstand the weight of a sewing machine as the sewing machine is carried by gripping the handle on the sewing machine itself. In other words, the portable case according to the invention need not be as strong as the conventional case that is provided with a handle on its top itself and has to bear the entire weight of the sewing machine. The portable one Housing according to the invention can therefore be light. Moreover, the portable case according to this invention can be made small be made. In particular, it can be short in the longitudinal direction because part of the flywheel of the sewing machine has The narrow side of the lid protrudes; it can also be low, as the lid can be made so simple. It can also
